Rule One ­ Negative Indices · a to the power of ­n is equal to 1 over a to the power of n ·The minus sign creates what is known as a reciprocal. ·Example: 2 to the power of -2 = ¼ or 2 to the power of -3 =…read more

Slide 3

Rule two: Fractional Indices ·a to the power of 1 over n is equal to the nth root of a ·For example: 8 to the power of is equal to 2 because 2 is the cubed root of 8 ·16 to the power of a half = 16 which =4…read more

Slide 4

Harder fractional indices ·These are a littler bit harder. But can easily be solved by doing one step at a time. ·For example: 27 can be split into (27 )² which can also be written as (³ 27)². ³ 27 = 3 3² = 9 and therefore 27 = 9…read more
